Question

*** 我的 nodemailer 不工作，邮件没有发送有错误***

const model = require("./usermodel")
const nodemailer = require("nodemailer")
const randomstring = require("randomstring")
const emailUser = process.env.emailUser
const emailpassword = process.env.emailpassword
const sendmail = async (name, email, token) => {
    const transpoter = nodemailer.createTransport({
        host: 'smtp.gmail.com',
        port: 587,
        secure: false,
        requireTLS: true,
        auth: {
            user: emailUser,
            pass: emailpassword
        }
    })
    const mailoption = {
        from: emailUser,
        to: email,
        subject: "reset password",
        html: '<p>hii' + name + ' ,copy link and <a href = "http://localhost:3000/reset-password ' + token + '">reset your password</a>'
    }
    transpoter.sendMail(mailoption, (error, inform) => {
        if (error) {
            console.log("error")
        } else {
            console.log("mail is send to email", inform.response);
        }
    })
}

const userregister = async (req, res) => {
    let body = req.body
    let create = await model.create(body)
    res.send(create)
}
const forgotpasswrod = async (req, res) => {
    const email = req.body.email
    const userdata = await model.findOne({ email: email })
    if (userdata) {
        const radonstring = randomstring.generate()
        const data = await model.updateOne({ email: email }, { $set: { token: radonstring } })
        sendmail(userdata.name, userdata.email, radonstring)
        res.send({ message: "please check your mail" })
    } else {
        return res.send({ message: "email not found" })
    }
}

module.exports = { userregister, forgotpasswrod }
